The introduction of a new technology by
comparing practice in different regions facing the same problems is expected
to have the following results:
1. The effective reduction of wastewater
load with the natural systems that are simple and inexpensive for their
design, construction and operation.
2. The possibility of restoring certain
3. Saving of energy and chemical
substances in comparison with the conventional wastewater treatment plants.
4. Tackling the seasonal peaks of
wastewater load mainly in the tourist regions (e.g.: Cyclades-Greece and
5. Effective reduction of the pathogen
microorganisms that can be achieved by this method.
1. Protection of the receiving water
bodies from the disposal of even the treated wastewater, whose quality is
inferior of that of the receiving body.
2. Reduction of the operational cost of
the wastewater treatment plants since there is no need to remove the
inorganic substances (nitrogen, phosphorous, potassium) because they can
be used as nutrients for the plants.
3. Reduction of the cultivation cost of
the farmers who use treated wastewater because of its concentration in
useful for the plants nutrients.
The introduction of permanent structures
i.e. natural systems in the treatment and reuse of wastewater, that will
continue their operation even after the period of Community financing has
finished. Thus, continuation of cooperation between partners will be
encouraged after the completion of the project.
The development of feasibility study for the
installation and operation of similar structures in a pilot scale, to the
areas that within the framework of the current project had acquired or
improved kno-how in the field (e.g. Bulgaria).
Since Cyclades is a complex of numerous
islands with serious water shortage which nowadays became more acute due to
the increasing tourist activities, the project in this area will have a
demonstration effect for the region. Varna (Bulgaria) is also area under
tourist pressure. The reclaimed water in this area could be used to irrigate
the local parks, which nowadays use good quality water.
